Be it known that l, Gnonon S. Qlflnm, a citizen of the United States, residin at Paterson, in the county of Passaic and tate of New Jersey, have invented certaln new and useful Improvements in Automatic Closure-Controlling Apparatus, of which the following is a specification.

This invention relates to automatic means for controlling movable closures, and its rincipal object is to provide a slm'ple, re- Eable, inexpensive and readily applied means for bringing about the closingof, for example, a window sash at any appointed time.

In the accompanying drawings- Figure 1 is an inside view of a window sash and its frame with my apparatus ap plied thereto;

Fig. 2 is a side elevation, partly in section;

Fig. 3 is a sectional view of the dog and detent of the tripping mechanism of my apparatus; and

Fig. 4c shows my apparatus arranged to control both a sash and the dampers of a furnace.

a designates the sash and 7) the frame in which it is arranged to move up and down in the usual way. The sash is preferably provided with means which tends to overcome the usual counterweights (not shown) and urge it downwardly; in the present instance this means is shown as a cylindrical holder 0 which is suitably secured upon the sash within the groove d in the frame 5 in which it travels and in which may be placed any number of weights 6, but any other expedient for normally urging the sash downwardly may be adopted.

A controlling member f, in the present case in the form of a cam lever, is ivoted to a suitable bracket 9' which is attac ed to the frame 6. This lever is so arranged that its shorter arm, which is preferably shod with a rubberpad f, is adapted to bear against the inner face of the sash, at which time the lever stands at an upwardly oblique angle to said face of the sa i There is a bracket k attached to the inner face of the frame 6 and to this is suitably secured a clock 2' having an actuating member a" which may be set to move at a iven time; if the clock is an ordinary a arm clock member 6' may be its alarm winding key or an extension thereof.

are also arranged the detent and do of means adapted to be tripped and controfiin the lever or member 7. The bracket has a laterally extending arm k in which is pivoted the detent, 7', whose right-hand end, underlying and adapted to be impinged and pressed downwardly by the member 6 of the clock, is normally held elevated b a s rin 75-; in the bracket is also pivote a d dg substantially a bell-crank lever, having a short upturned arm adapted to bear at its inner side against the end of the detent and a long laterally projecting arm which underlies the detent.

Another bracket m is afixed to frame 6 below bracket 7i and in this is fulcrumed a lever n. Que arm of this lever is connected by the flexible connection 0 with the long arm of the dog Z, its other arm is connected with the long arm of the controlling member f by a flexible connection 37 which includes a spiral spring 9.

till

The control of furnace dampers may also A allow damper B to close and open damper A. A flexible connection h extends from hook E over a pulley G and has a ring H and a weight I attached to its free end.

The ring may be hooked over a pivoted arm J which is held horizontally, in position to support the weight, by a flexible connection K extending up to that arm of lever n to which connection 0 is attached, 1;. a, when lever n is itself held in the position shown in full lines by dog Z and detent 3'; when lever n shifts to the dotted lineposition arm J falls and the weight ll descending the position of the dampers is reversed, as will be apparent.

The sash' having been raised to' the desired hei ht the operator shifts the dog Z to the ful -line position in Fig. 3, upon which the ,detent will spring in position to hold it there. The moyement of the dog has, through the described connections, caused the rubber-shod end of member 7 to bear against the sash thus by friction to retain the latter at the elevation to which it has ioo been moved. When member 2'' of the clock 21 having its movement in one direction limited is released at the predetermined time it-impinges detent j and moves it clear of dog l which, falling, releases lever f and permits the sash to fall. Spring 9 not only imposes a certain amount of desirable tension on dog Z when it is held by the detent but makes it unnecessary to set the brackets g, h and m in always precisely the same spacing from each other. Lever acts substantially as a cam to prevent upward movement of the sash so that it cannot be opened further than the distance set. On the other hand said lever will allow the sash to be pushed down even when the lever is in the holding position; this is an advantage when some other element than the sash is to be controlled, as the furnace dampers. A and B, and it is desired to close the sash and leave the other element under time controL' An additional advantage of spring 9 is that it permits lever f to be moved to allow the sash to be, raised without disturbing lever Z and consequently the dampers.

Having thus fully described what I claim is:

1. In combination, with supporting means, a controlling member having movement therein back and forth and its movement in one direction limited thereby, elastic trippable means normally holding said member at said limit, and time means for tripping said trippable means.

2. In combination, a fixed structure, a closure movable therein, a controlling member my invention,

' for the closure having movement in said structure back and forth and having its movementin one direction limited by the closure, and elastic trippable means normally holding. saidmember at said limit.

3. In combination, a fixed structure, a closure movable therein, a controlling friction brake member for the closure having movement in said structure back and forth and bythe closure, and elastic trippable means normally holding said member at said limit.

4. In combination, a fixed structure, a closure movable therein, a controlling cam member for the closure having pivoted movement in said structure back and forth and having its movement in one direction limited by the closure and elastic tri pable means normally holding said mem er at said limit.

5. In combination, a frame structure, a sash movable u and down and normally urged downwar ly in said structure, a controlling member normallyengaging the sash and opposing greater resistance to upward than to downward movement thereof, said member being movable in the frame structure away from'the sash, and trippable means normally holding said member engaged with the sash.

6. In combination, a frame structure, a sash movable 11 and down and normally urged downwar ly in said structure, a controlling member normally frictionally en gaging the sash and opposing greater resistance to upward than to downward movement thereof, said member being movable in the frame structure away from the sash, and elastic trippable means normally pressing said member against the sash.

7. In combination, with the movable member to be controlled, said member having limited movement,-a pivoted dog, an elastic connection between said member and the dog, said dog being movable to a definite GEORGE S. ONEIL.'
